2027 Notre Dame Online MS in Data Science vs. Harvard Extension Data Science and AI ALM: Cost, Curriculum, Admissions, and Format
Notre Dame's online MS in Data Science and Harvard Extension School's Data Science and AI ALM present different choices for working professionals. The decision is not simply which university name you prefer: degree designation, admission route, campus attendance, coursework, and total cost may affect whether either program fits your life and career plans. This comparison separates established differences from details you should confirm for your intended enrollment term, so you can decide which program merits an application.
Key Things You Should Know
- Notre Dame offers an MS in Data Science; Harvard Extension offers a Master of Liberal Arts (ALM) in Extension Studies in the field of Data Science and AI. Compare the credential that will appear on your transcript, not just the program's promotional name.
- Harvard Extension's degree includes a campus component, while Notre Dame markets its MS as an online program. Confirm current attendance requirements before treating either as compatible with a no-travel schedule.
- Neither program's degree alone establishes a salary outcome: the U.S. Bureau of Labor Statistics reports a $120,230 median annual wage for data scientists in May 2025, across workers with varied education and experience.
How Do Notre Dame and Harvard Extension's Data Science Master's Programs Compare?
The distinction begins with the credential and the way students enter and attend the program. The table uses the same decision criteria for both schools; requirements that can change should be checked against the catalog for your enrollment term.
| Decision factor | Notre Dame online MS in Data Science | Harvard Extension Data Science and AI ALM |
| Degree | Master of Science in Data Science | Master of Liberal Arts (ALM) in Extension Studies, field of Data Science and AI |
| Program emphasis | A data science graduate program | A data science program that explicitly incorporates AI into its field of study |
| Entry route | Apply through the program's graduate admissions process | Complete designated courses and meet Extension School's degree-admission rules |
| Location constraint | Marketed as online; verify any live or in-person obligations | Online study with an on-campus degree requirement |
| Cost comparison | Confirm current program tuition and mandatory charges | Confirm current per-course charges, required courses, and campus-related costs |
The ALM is a Harvard University degree awarded through Harvard Extension School; it should not be described as an MS or as a degree awarded by another Harvard school. Conversely, Notre Dame's MS title does not, by itself, establish that its courses are more technical. Course requirements and substantial project work are better evidence of skill depth than either degree label.
What Do Notre Dame and Harvard Extension Data Science Degrees Cost?
A reliable 2026 price comparison requires the tuition schedule for the term in which you will enroll and each school's current degree requirements. A verified, like-for-like total for both programs is not established here, so assigning either school a lower sticker price would be misleading. In particular, a per-course Harvard Extension price cannot be compared directly with a Notre Dame full-program quote.
Calculate each school's estimated cost to completion by multiplying applicable tuition rates by required courses or credits, then adding mandatory fees. Separately budget for books or software, financing costs if you borrow, and any travel, lodging, or time away from work required for campus attendance. Ask whether an employer's tuition benefit covers Extension School courses taken before formal degree admission; that timing can change your out-of-pocket cost.
Request written answers from both schools on tuition changes during enrollment, fees, payment timing, financial-aid eligibility, and the treatment of previously completed coursework. The common mistake is to compare advertised tuition alone while leaving out Harvard's campus expenses or assuming either school will hold today's rate for the entire degree.

How Do the Programs Differ in Curriculum and Coursework?
Harvard Extension's field name makes AI an explicit part of the degree's identity. Notre Dame's degree name centers data science. Neither name tells you how much time you will spend building models, engineering data pipelines, studying statistical inference, or evaluating AI systems. For a useful comparison, examine the required - not merely available - courses in the catalogs for your intended term.
Compare the sequence in three layers: mathematical and programming foundations; statistics, machine learning, and AI methods; and applied work such as a substantial project or capstone. Then check which electives you can realistically take given prerequisites and scheduling. If your goal is building reliable data infrastructure rather than primarily training models, compare both catalogs with AI master's course options for data engineering.
Ask each program for a sample study plan showing when required courses are offered and whether the final project can address your intended industry. A course title mentioning AI is less persuasive than assessed work involving implementation, evaluation, and communication of results.
What Are the Online and Campus Format Options?
Notre Dame presents this MS as an online program. Harvard Extension combines online coursework with an on-campus requirement for the degree. That difference matters if travel is impossible or if you value some in-person study enough to arrange time and money for it. Do not assume "online" means self-paced or that a campus requirement can be completed whenever you choose.
Before enrolling, ask both programs which classes have scheduled live meetings, what time zone governs them, whether group projects require real-time collaboration, and whether exams have fixed windows. Ask Harvard Extension specifically which campus options satisfy the current degree rule, when they run, and whether the courses you need are available in a workable sequence. Ask Notre Dame whether any orientation, residency, or other activity requires travel. These operational details can outweigh a modest tuition difference for someone working full time.
What Are the Admission Requirements for Each Program?
The entry routes differ. Notre Dame uses a graduate-program application; Harvard Extension uses an earn-your-way-in model involving specified coursework and performance before degree admission. Taking a Harvard Extension course is therefore not the same as already being admitted to the ALM. For either school, rely on its current admissions page for exact course, grade, documentation, and deadline rules rather than assuming requirements from another master's program apply.
Evaluate your readiness separately from formal eligibility. If your background is light on programming, statistics, or mathematics, ask which skills are expected before the first course and which can be developed during the program. AI master's programs with preparatory coursework can provide a point of comparison, but outside preparation should not be assumed to satisfy either school's admissions rules. Harvard applicants should also clarify whether qualifying courses must be taken within a particular period and how credits earned before admission count toward the degree.

How Long Do the Data Science Master's Programs Take?
Your completion time depends on course load, course availability, required sequencing, and - for Harvard Extension - the timing of admission and campus study. A published fastest-possible schedule is not a reliable personal timeline if you can take only one course at a time or must wait for a prerequisite to run.
Ask each school for a term-by-term plan based on your actual work schedule, including the earliest realistic final-project term and any maximum time allowed to finish. Harvard applicants should count required pre-admission coursework in the calendar, even if those courses later apply to the degree. If finishing quickly is a leading priority, use a data science master's time-to-completion guide to identify the pacing questions to put to both schools.
What Data Science Careers Can Graduates Pursue?
Depending on prior experience and demonstrated skills, either program could support applications for data scientist, machine learning, analytics, or related roles. The better match depends on the work you want to show employers: statistical analysis and decision support, model development, or production-oriented data and AI systems. A degree may strengthen that evidence, but it does not replace relevant projects or experience.
Compare job descriptions for your target role with the required courses and project options in each program. If the roles you want focus more on reporting, experimentation, and business decisions than on developing AI systems, it may also be useful to find a data analytics master's program before committing to either option. The Bureau of Labor Statistics projects 35% growth in U.S. data scientist employment from 2025 to 2035; that signals demand across the occupation, not a placement forecast for either school.
What Salaries Can Data Science Master's Graduates Expect?
The U.S. Bureau of Labor Statistics reports a $120,230 median annual wage for data scientists in May 2025. This is an occupational median across workers with different backgrounds, employers, locations, and levels of experience - not the starting salary or expected salary increase for a graduate of either program.
For a personal financial comparison, use salary ranges for the roles and locations you would actually pursue, then compare those prospects with your total education cost and any earnings you would give up while studying. If either school provides graduate outcomes, check the graduating group, response rate, prior work experience, and whether the figure describes salary level or salary change. Treat a promise that the degree will "pay for itself" without those details as a warning sign.
Is Accreditation or Professional Licensing Required for Data Scientists?
Data scientist is not generally a state-licensed occupation in the United States, and neither program should be evaluated as a route to a data scientist license. Some specialized jobs may impose employer, industry, or security requirements; those are separate from a general professional license.
For education due diligence, confirm each university's current institutional accreditation through the institution and its recognized accreditor. Do not assume that the absence of a profession-specific data science accreditation makes a degree invalid, or that institutional accreditation guarantees an employer will prefer one curriculum. For this decision, the credential awarded, coursework, and evidence of applied skill are more informative distinctions.
Which Data Science Master's Program Should You Choose?
Choose Notre Dame for closer consideration if you specifically want an MS in Data Science and its confirmed online schedule, courses, and full cost fit your circumstances. Choose Harvard Extension for closer consideration if its ALM credential and Data Science and AI curriculum fit your goals, you are comfortable proving eligibility through designated coursework, and you can meet the campus requirement. Neither is a universal winner on price, technical depth, or career outcomes without a current, individualized comparison.
Make the final decision using written answers from both schools on your complete cost, a workable term-by-term schedule, required campus attendance, and the courses and project you would actually complete. If AI is central to your plans, assess whether those courses support aligning AI study with your intended career rather than choosing on the strength of a program name. If a required course, travel commitment, or pre-admission expense is still unclear, resolve it before paying a deposit or registering.
Other Things You Should Know About Data Science
Not necessarily. Ask each registrar for the official degree wording and how the field of study appears on the transcript and diploma, especially if the distinction between an MS and an ALM matters to you.
Possibly, but ask about project approval, employer permission, confidentiality, and restrictions on using proprietary data before planning around a workplace dataset.
That depends on the course and current admissions rules. Review the prerequisites for the first required class you intend to take; being permitted to enroll does not necessarily mean an introductory programming course will be part of the degree.
Transfer and prior-course rules are program-specific. Obtain written confirmation of whether a particular course counts, how it affects remaining requirements, and whether accepting it changes your financial-aid eligibility or study plan.
